Question
If Xᴴ = dominant allele and Xʰ = recessive allele, would an individual with a XᴴXʰ genotype be considered a carrier?

Solution
Explanation of Carrier Status
-
Understanding Alleles: In genetics, alleles refer to different versions of a gene. The dominant allele (Xᴴ) can mask the presence of the recessive allele (Xʰ), and thus, an individual carrying one dominant allele (Xᴴ) and one recessive allele (Xʰ) can display the phenotype associated with the dominant trait.
-
Genotype of Interest: The individual with the genotype XᴴXʰ possesses one dominant allele and one recessive allele. This means the dominant trait is expressed phenotypically.
-
Definition of Carrier: A carrier is typically defined as an individual who has one copy of a recessive allele for a particular trait but does not express that trait phenotypically. Carriers can pass the recessive allele to their offspring.
Conclusion
In this context, since the individual with genotype XᴴXʰ expresses the dominant phenotype due to the presence of Xᴴ but carries the recessive allele (Xʰ), they would indeed be classified as a carrier for the recessive trait. Thus, the correct answer to your question is:
Answer: Yes
